Description

本発明は、ゴムボートに係り、特に膨張式のゴムボートに関する。   The present invention relates to a rubber boat, and more particularly to an inflatable rubber boat.

膨張式のゴムボートには、船外機を搭載する型式（以下、船外機型式とも記す）と、オールで漕ぐ型式（以下、オール型式とも記す）とがあり、オール型式のゴムボートは、船外機型式のゴムボートに比べて操縦性に対する要求が低く、船底部分の構造もキールが存在しない簡便なものでよい。例えば、オール型式のゴムボートの基本的な構造としては、所望の形状に形成された床布の外周に気室を接合した構造となっている（特許文献１）。   There are two types of inflatable rubber boats, one with an outboard motor (hereinafter also referred to as outboard motor type) and the other with a rowing type (hereinafter also referred to as all type). Compared to the inflatable rubber boat, the requirements for maneuverability are low, and the structure of the bottom of the ship may be simple with no keel. For example, the basic structure of an all-type rubber boat has a structure in which an air chamber is joined to the outer periphery of a floor cloth formed in a desired shape (Patent Document 1).

このようなオール型式のゴムボートは、キールが存在しないので、気室に設けられた空気注入口からの空気の注入により気室を膨張させることにより、容易に使用可能な状態とすることができる。また、気室に設けられた空気排出口から空気を排出することによりコンパクトに折り畳むことができるので、保管、運搬が容易である。このため、緊急時の取扱が容易であり、例えば、災害時等における救助用ゴムボートとしての使用が可能である。   Since such an all-type rubber boat does not have a keel, it can be easily used by inflating the air chamber by injecting air from an air inlet provided in the air chamber. Moreover, since air can be folded compactly by discharging air from the air discharge port provided in the air chamber, storage and transportation are easy. For this reason, it is easy to handle in an emergency, and can be used as a rescue inflatable boat in a disaster, for example.

尚、図面は模式的または概念的なものであり、各部材の寸法、或いは、各部材間の寸法の比等は、必ずしも現実のものと同一とは限らず、また、同じ部材等を表す場合であっても、図面により互いの寸法や比が異なって表される場合もある。 Embodiments of the present invention will be described with reference to the drawings.
The drawings are schematic or conceptual, and the dimensions of each member or the ratio of dimensions between the members are not necessarily the same as the actual ones. Even so, the dimensions and ratios may be different depending on the drawing.

図１は、本発明のゴムボートの使用状態における一実施形態を示す平面図であり、図２は、図１に示されるゴムボートのＩ−Ｉ線における拡大縦断面図である。図１および図２において、本発明のゴムボート１１は、環状の気室１２と、この気室１２に接合された床布１３と、補強布１４と、を有し、補強布１４は、床布１３の船底側１３ａ、および、気室１２の少なくとも船底側の外側壁１２ａを被覆している。   FIG. 1 is a plan view showing an embodiment of the rubber boat of the present invention in use, and FIG. 2 is an enlarged longitudinal sectional view taken along line II of the rubber boat shown in FIG. 1 and 2, a rubber boat 11 according to the present invention includes an annular air chamber 12, a floor cloth 13 joined to the air chamber 12, and a reinforcing cloth 14. The reinforcing cloth 14 is a floor cloth. 13 of the ship bottom side 13a and the outer wall 12a of at least the ship bottom side of the air chamber 12 are covered.

図示例では、床布１３の外形がやや細長い六角形であり、この床布１３の周囲に気室１２が接合されている。気室１２は、気室１２Ａと気室１２Ｂとが接着剤で接合された２段構造を有しており、船底側（使用時の下段側）の気室１２Ａと床布１３とが接着剤で接合されている。この船底側の気室１２Ａの外側壁１２ａには接合部材１５が設けられている。そして、気室１２Ａの外側壁１２ａと床布１３の船底側１３ａを被覆する補強布１４の端部１４ａが接着剤で接合部材１５に接合されている。このように気室１２が２段構造を有することにより、仮に気室１２Ａと気室１２Ｂのいずれか一方が破損した場合でも、残りの気室により十分な浮力が得られるように設計することによって、十分な安全性が得られる。尚、気室１２の段数は２段に限定されず、３段以上の多段であってもよい。   In the illustrated example, the outer shape of the floor cloth 13 is a slightly elongated hexagon, and the air chamber 12 is joined around the floor cloth 13. The air chamber 12 has a two-stage structure in which the air chamber 12A and the air chamber 12B are joined by an adhesive, and the air chamber 12A and the floor cloth 13 on the ship bottom side (the lower tier side in use) are adhesive. It is joined with. A joining member 15 is provided on the outer wall 12a of the air chamber 12A on the ship bottom side. And the edge part 14a of the reinforcement cloth 14 which covers the outer wall 12a of the air chamber 12A and the ship bottom side 13a of the floor cloth 13 is joined to the joining member 15 with an adhesive. By designing the air chamber 12 to have sufficient buoyancy even if one of the air chamber 12A and the air chamber 12B is damaged, the air chamber 12 has a two-stage structure. Sufficient safety can be obtained. Note that the number of stages of the air chambers 12 is not limited to two, and may be three or more stages.

２段構造の気室１２を構成する気室１２Ａ，１２Ｂは、断面形状が円形となるように形成されており、材質は柔軟性を有すると共に所望の強度を有し気密性に優れたゴム引き布であってよく、例えば、国土交通省が定める救命いかだの型式承認試験基準の膨脹式いかだの材料試験（主気室、天幕支柱気室及び床を構成するゴム引き布の試験）に準拠した判定基準を満足するゴム引き布を使用することができる。このような気室１２を構成する気室１２Ａ，１２Ｂには、それぞれ空気注入口（図示せず）と空気排出口（図示せず）が設けられている。尚、空気注入口が空気排出口を兼ねるものであってもよい。また、必要に応じて、気室１２を構成する気室１２Ａ，１２Ｂに加圧防止用の安全弁を設けてもよい。   The air chambers 12A and 12B constituting the air chamber 12 having a two-stage structure are formed so that the cross-sectional shape is circular, and the material is flexible, and has a desired strength and is excellent in airtightness. It may be a cloth, for example, in conformity with the material test of the inflatable raft (test of the rubberized cloth constituting the main air chamber, awning column air chamber and floor) of the life raft type approval test standard established by the Ministry of Land, Infrastructure, Transport and Tourism A rubberized cloth that satisfies the criteria can be used. Each of the air chambers 12A and 12B constituting the air chamber 12 is provided with an air inlet (not shown) and an air outlet (not shown). The air inlet may also serve as the air outlet. Moreover, you may provide the safety valve for a pressurization prevention in air chamber 12A, 12B which comprises the air chamber 12 as needed.

また、床布１３の材質は、柔軟性を有すると共に所望の強度を有し気密性に優れたゴム引き布であってよく、例えば、国土交通省が定める救命いかだの型式承認試験基準の膨脹式いかだの材料試験（主気室、天幕支柱気室及び床を構成するゴム引き布の試験）に準拠した判定基準を満足するゴム引き布を使用することができる。この床布１３は、上記の気室１２と同じゴム引き布であってもよい。   The material of the floor cloth 13 may be a rubberized cloth having flexibility, desired strength and excellent airtightness. For example, an expansion type of a life raft type approval test standard defined by the Ministry of Land, Infrastructure, Transport and Tourism It is possible to use a rubberized cloth that satisfies the criteria based on the raft material test (the test of the rubberized cloth constituting the main air chamber, the awning column air chamber, and the floor). The floor cloth 13 may be the same rubberized cloth as the air chamber 12 described above.

また、接合部材１５は、補強布１４の端部１４ａから気室１２Ａに作用する外力を緩和し、気室１２Ａを保護するものであり、例えば、気室１２と同じゴム引き布を接着剤で気室１２Ａに接合したものであってよい。このような接合部材１５は、船底側の気室１２Ａの外側壁１２ａの周囲に連続した状態で設けることができ、また、所定間隔で設けてもよく、配設位置は、補強布１４を保持可能なように適宜設定することができる。   Moreover, the joining member 15 relieves the external force that acts on the air chamber 12A from the end portion 14a of the reinforcing cloth 14, and protects the air chamber 12A. For example, the same rubberized cloth as the air chamber 12 is bonded with an adhesive. It may be joined to the air chamber 12A. Such a joining member 15 can be provided continuously around the outer wall 12a of the air chamber 12A on the ship bottom side, and may be provided at a predetermined interval. The arrangement position holds the reinforcing cloth 14. It can be set appropriately as possible.

本発明のゴムボート１１を構成する補強布１４は、柔軟性を有すると共に所望の強度を有する繊維布である。補強布１４に使用する原糸に要求される物性としては、例えば、耐摩耗性及び耐屈曲疲労性が１００００サイクル以上、耐突き刺し性が４００Ｎ以上、耐候性が原強の８０％以上のような物性が挙げられる。このような補強布１４としては、例えば、東洋紡（株）製 ダイニーマ等の有機繊維等が挙げられる。また、補強布１４は、上記のような物性を具備した原糸を使用した繊維布とともに、例えば、ガラス繊維、カーボン繊維、アラミド繊維等を組み合わせて使用したものであってもよい。   The reinforcing cloth 14 constituting the rubber boat 11 of the present invention is a fiber cloth having flexibility and desired strength. The physical properties required for the yarn used for the reinforcing fabric 14 include, for example, a wear resistance and a bending fatigue resistance of 10,000 cycles or more, a puncture resistance of 400 N or more, and a weather resistance of 80% or more of the original strength. Physical properties are listed. Examples of such a reinforcing cloth 14 include organic fibers such as Dyneema manufactured by Toyobo Co., Ltd. In addition, the reinforcing cloth 14 may be a combination of a fiber cloth using a raw yarn having the above physical properties and a combination of glass fiber, carbon fiber, aramid fiber, and the like.

このような本発明のゴムボート１１は、空気注入口（図示せず）から気室１２Ａ，１２Ｂに空気を注入し膨張させて迅速に使用する状態とすることができる。また、気室１２Ａ，１２Ｂ内の空気を空気排出口（図示せず）から抜いてコンパクトに折り畳むことができ、運搬が容易であり、保管場所の省スペース化が可能である。そして、船底側の気室１２Ａの外側壁１２ａと床布１３の船底側１３ａを被覆する補強布１４を有しているので、ゴムボート１１の使用時にがれき等と接触しても、気室１２、床布１３が保護されて使用時の耐久性に優れ、高い信頼性を具備している。   Such a rubber boat 11 of the present invention can be put into a state of being used quickly by injecting air from the air inlet (not shown) into the air chambers 12A and 12B and expanding the air. Further, the air in the air chambers 12A and 12B can be drawn out from an air outlet (not shown) and folded in a compact manner, so that it can be easily transported and the storage space can be saved. And since it has the reinforcing cloth 14 which coat | covers the outer side wall 12a of the air chamber 12A of ship bottom side, and the ship bottom side 13a of the floor cloth 13, even if it contacts with debris etc. at the time of use of the rubber boat 11, the air chamber 12, The floor cloth 13 is protected, has excellent durability during use, and has high reliability.

また、補強部１４が繊維布であるため水の透過が可能であり、図３に示すように、ゴムボート１１の使用時に床布１３と補強布１４との間隙部１７に水（図３では鎖線状の斜線を付して示している）が侵入し、この部位が安定水嚢あるいはバラストとしての機能を発現する。したがって、本発明のゴムボート１１は、波や風による転覆が生じ難いものである。   Further, since the reinforcing portion 14 is a fiber cloth, water can be transmitted. As shown in FIG. 3, when the rubber boat 11 is used, the gap portion 17 between the floor cloth 13 and the reinforcing cloth 14 has water (a chain line in FIG. 3). (Shown with a diagonal line) invades, and this site develops a function as a stable water sacs or ballast. Therefore, the rubber boat 11 of the present invention is not easily overturned by waves or wind.

図４は、本発明のゴムボートの使用状態における他の実施形態を示す平面図であり、図５は、図４に示されるゴムボートのII−II線における拡大縦断面図である。図４および図５に示されるゴムボート１１では、床布１３の船底側１３ａの一部に接合部材１６が設けられ、この接合部材１６に接着剤で補強部１４が接合されている。接合部材１６は、補強布１４から床布１３に作用する外力を緩和し、床布１３を保護するものであり、例えば、床布１３と同じゴム引き布を接着剤で床布１３に接合したものであってよい。   FIG. 4 is a plan view showing another embodiment of the rubber boat of the present invention in use, and FIG. 5 is an enlarged longitudinal sectional view taken along line II-II of the rubber boat shown in FIG. In the rubber boat 11 shown in FIGS. 4 and 5, a joining member 16 is provided on a part of the ship bottom side 13 a of the floor cloth 13, and the reinforcing portion 14 is joined to the joining member 16 with an adhesive. The joining member 16 is for relaxing the external force acting on the floor cloth 13 from the reinforcing cloth 14 and protecting the floor cloth 13. For example, the same rubberized cloth as the floor cloth 13 is joined to the floor cloth 13 with an adhesive. It may be a thing.

このように、床布１３と補強部１４とを一部で接合することにより、例えば、ゴムボート１１を船外機付きボートで曳航する際の補強布１４の波打ち変形等による抵抗を低減することがでるとともに、上述のように、床布１３と補強布１４との間隙部１７に水が侵入し、この部位が安定水嚢やバラストとしての機能を発現する。
尚、接合部材１６を設ける位置、接合部材１６の数、形状は、図示例に限定されるものではない。 Thus, by joining the floor cloth 13 and the reinforcing portion 14 in part, for example, the resistance due to the undulating deformation of the reinforcing cloth 14 when towing the rubber boat 11 with the boat with an outboard motor can be reduced. At the same time, as described above, water enters the gap 17 between the floor cloth 13 and the reinforcing cloth 14, and this part develops a function as a stable water sacs or ballast.
The positions where the joining members 16 are provided, the number and shape of the joining members 16 are not limited to the illustrated examples.
